About

Renew Power Systems, Inc. (RPSi), now operating as SYNCRIS, is a Minneapolis company that designs and manufactures grid-forming power inverters for microgrids. Its patented hardware-based power controls let paralleled inverters self-balance, share load, and absorb power surges, which simplifies microgrid operation and maintenance and keeps the system component-agnostic. The inverters are stackable, rack-mountable, silicon-carbide, fanless units built in Minnesota and sold nationally, largely through microgrid installers serving commercial and industrial sites. The technology was developed by University of St. Thomas electrical engineering professor Greg Mowry with Zach Emond, and Scott Tracy is chief executive.

Power controls implemented in hardware rather than a central controller, so networked inverters self-balance and load-share on their own — which the company positions as both a maintenance and a cybersecurity advantage — combined with 100% US manufacturing that helps buyers qualify for grant funding.

Product

SYNCRIS Inverters

Power electronics hardware

Stackable, rack-mounted power inverter modules for grid-connected and off-grid microgrids. Paralleled units respond in unison to balance load and manage surges without central control, and stack to produce single-, two-, three-, and poly-phase output.

  • Stackable, rack-mountable modules producing single-, two-, three-, and poly-phase output
  • Silicon carbide (SiC), fanless design
  • Hardware-based controls for self-balancing, load sharing, and surge management across paralleled inverters

Built for

Microgrid installers and resellers serving commercial and industrial end users, plus grant-funded and defense-adjacent buyers that require US-manufactured equipment
